Patent FR-2342921-A1 (FR)
Title: Transfer of rusks etc. from oven to wrapping machine - with automatic reorientation and arrangement in counted sets
IPC: B65B23/14
Filed: 1976-03-05
Abstract: A machine for transferring rectangular slices of a prod. e.g. rusks, squares of toast etc. to a wrapping machine from a horizontal conveyor belt on which the slices are received lying flat on the belt in regular, spaced transverse ranks and longitudinal files. The slices in each file are rearranged in upright positions and collected into aligned, counted sets. The sets are passed in succession to the infeed of a wrapping machine. The slices in each file are pref. divided as they leave the horizontal conveyor, alternate slices being directed to two rearranging and counting devices operating in parallel. The slices for each rearranging device are pref. taken from the horizontal conveyor belt between upper and lower, foam-covered, narrow bands. The slices are punched by rotary brushes through an aligning corridor with laterally oscillating side-walls. They are then brought to an upright position by releasing them, one at a time, down an inclined plane to be counted into sets.

Title: Pulsed nuclear magnetic resonance technique - includes generation of intense magnetic field pulses and amplification of signal received from sample for computer analysis
IPC: G01R33/46
Filed: 1976-05-06
Abstract: A system generates high frequency, high power pulses during a time period D1 and these pulses create an intense magnetic-field in the region where the sample to be analysed is placed. The signals emitted by the sample are received and amplified and a computer treats and records these signals. The supply to the receiver/amplifier system is cut off and earthed and then, after an adjustable time period D2, it is reconnected to the voltage line. The output of the receiver/amplifier system is earthed during an adjustable time period D3, so that the output is earthed while the supply is cut off and returned to the voltage line. The high frequency, high power pulses are generated during the periods D2 and D3.

Title: Telephone exchange semi-automatic switching - allows operators intervention without using three line networks
Inventor: COLIN PIERRE GEORGES HENRI
IPC: H04Q3/00
Filed: 1976-12-30
Abstract: The switching circuit is for basically automatic exchanges, where operator assistance and monitoring is required in order to assist subscribers, particularly w.r.t. international calls, to obtain their required connections. The circuit allows the operator, from a switching console to speak to the caller and the called number without having recourse to complex three line networks. The circuit is based on the use of a unique switching network, ensuring the connection of switching circuits to the operator and also the connection of outgoing lines to individual equipments associated with the inward and outward going lines of the exchange. Line selection is computer assisted but can be maintained if this is out of order.

Title: More rapid mixed acid polyesters prodn. - by reacting aromatic acid with only a portion of the polyol in a first stage, then adding remainder and aliphatic acid
Inventor: LACONA JOSEPH
IPC: C08G63/54
Filed: 1977-05-17
Abstract: A 2-stage process for making polyesters (I) comprises reacting in a first stage isophthalic or terephthalic acid with sufficient of the polyol (II) to form an agitatable mixt but slightly less than the theoretical amt. needed to react with aromatic acid and the (subsequently added) (un)satd. aliphatic polycarboxylic acid (III). The mixt. is heated at >=190-230 degrees C, than the rest of (II) is added such that the temp. does not fall below 190 degrees C to give a Y2-ester mixt. This mixt. is than reacted in a second stage with (III) to produce (I). Processing time in the first stage, and thus in the overall process, is reduced, e.g. from 11 1/4 to 7 1/2 in the examples.
